Standard Operation Procedures of Password Bypassing and BIOS Recovery for TravelMate 2420/Aspire 3620
For RD and CSD to debug easily, TM2420/AS3620 provides one hardware PIN pad for Bypassing Password Check, and one Hotkey to enable BIOS Recovery.
1. PIN pad : To short PIN pad to bypass password check.
2. Hotkey to enable BIOS Recovery: Fn+ESC, then Power Button, AC+DC coexistence is strongly recommended.
Bypassing Password Check : If the user has set Password (power-on or setup password) for security reason, BIOS will check password during POST or when entering the BIOS setup menu. However, if it is necessary to ignore the password check, the user may enable short PIN Pad to bypass password check.
BIOS Recovery: Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS initialization. The user can enable this feature to restore the BIOS to a successful one if previous BIOS flashing process fails.

1. Clear Password
PIN Pad: Bypassing Password Check, Keep shorting EC44(2 square pad) or G12 (2 triangle pad)as above PIN pad and then powering on the system will force the BIOS to clear Supervisor and User passwords. That means both the power-on and setup passwords, and the HDD password are all cleared.
2. Restore BIOS by the Crisis Disk
Enable this function by Fn+ESC, and Power Button. To use this function, it is strongly recommended to have the coexistence of AC and Batter powers. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called BootBlock. RD/CSD can use this special BIOS code to recover the BIOS to a successful one if previous BIOS flashing process fails. However, before doing this, one Crisis Disk should be prepared in WinXP. Detailed steps are as the followings,
2.1 Prepare the Crisis Disk in WinXP (Crisis Disk will be released when BIOS V1.00 is released)
2.2 Insert the Crisis Disk to a USB floppy drive which is attached to the failed machine.
2.3 On the power-off state, press Fn+ESC, hold them, then press button. The system should be powered on with Crisis Recovery process.
2.4 BootBlock BIOS starts to restore the failed BIOS code. Short beeps should be heard when flashing.
2.5 If the flashing process is finished, a long beep should be heard.
2.6 Power down the system when Step 3.5 is finished.
If the crisis recovery process is finished, the system should be powered on with a successful BIOS. RD/CSD can then update the BIOS to a workable one by regular BIOS flashing process.
